How Do I Decode a Base64 Encoded String?

Decoding a Base64 Encoded String

This article will guide you through the process of decoding a Base64 encoded string, enabling you to uncover the original content it represents.

Understanding Base64 Encoding

Base64 encoding is a technique used to represent binary data as a string of printable characters. It is often used for encoding data that is stored or transmitted over channels that may not support binary data.

Decoding a Base64 String

To decode a Base64 encoded string, you can follow these steps:

1. Convert the Base64 string to a byte array. This can be done using the Convert.FromBase64String method.
2. Decode the byte array into a string. This can be done using the System.Text.Encoding.UTF8.GetString method.

Here is an example code snippet that demonstrates how to decode a Base64 encoded string:

byte[] data = Convert.FromBase64String(encodedString);
string decodedString = System.Text.Encoding.UTF8.GetString(data);

Specific Case Example

In the provided example, you have a Base64 encoded string that has been further processed. To decode this string, you will need to perform the following steps:

1. Convert the Base64 encoded string to a byte array using the Convert.FromBase64String method.
2. Decode the byte array into a string using the System.Text.Encoding.UTF8.GetString method.

This will provide you with the original string that was encoded.
